For those patient enough to follow my recent threads looking got help, thanks for the hints.

I successfully installed a Kenwood DNX7240BT and although it wasn't without some issues it was fairly straight forward. I am not a auto electrician but I am an IT guy. So if you can understand a few wiring diagrams you can do it too. I am not the first (and would like to say the info on Planet-9 help tremendously) but being as this is a fairly recent unit it may give others the confidence to give it a crack if they too want 21st century ICE to go with their 21st century car!

The major caveats are;
I have NO BOSE
and I don't have the sound upgrade package either.
This means I can avoid the fibre optic issues others may encounter.

Looks good, I wanted to upgrade to PCM2.1 from my CDR24, but seems to be abit of a ball ache, this looks a good system. Where did you get it from if you don't mind me asking?

Also where did you get the facia adaptor?

Cheers

If your PCM2.1 is BOSE or sound upgrade it will be v.expensive and probably not worth it. If not read on.

I'd contemplated buying a 2.1 HU and then adding all the parts but it would still have cost me thousands and quality/integration wise it would have still been pretty "dark ages" in comparison.

I think what annoyed me and spurred me into action was 20 years ago I had a car with a 10 CD changer, and 10 years ago I bought a HU for my Elise that I still managed to easily upgrade for iPOD with limited functionality (masquerading as a CD changer) for small beer several years later. The fact that all these options for the Porsche setup (whichever one you had) seemed to be several hundred pounds made me pretty determined to find a better solution that still looked compatible. (notice the lack of rotary knobs)

Got the HU off ebay for at less than half price of new.

The fascia is made by Autoleads and is available through many internet outlets for around £40 with fitting kit.

You'll also need Autoleads adaptor(s) to plug the Porsche aerial lead into an aftermarket stereo (thinks it's ISO to DIN but could be the other way around = Halfords £25 much cheaper but longer lead time on-line)

In your position it depends how functional your PCM2.1 is. IF it s enabled with SATNAV/Phone it may be difficult to extract... if it isn't you could probably sell it on ebay and easily cover all the costs I encountered.

The one thing I have lost is the line that feeds info to the speedo. I get - - - - instead of Radio 1/TPS INFO/CDS T1 etc. big deal. I've now got a much clearer display to look at if that's important to me.

I haven't bought a PCM headunit yet, was going to buy one off eBay last week that went for £400, but after reading various threads on www.boxa.net I chickened out, also thinking about changing to a 993, so would of been pointless buying the system. At the minute I've got CDR24 with the upgraded sound package. I just want a head unit with a decent display, decent sat nav (am I right in saying yours has a Garmin sat nav on it?) and to be able to use my iPod easily.

Looks very nice - far far better than original. What sort of issues are likly to be encountered with PCM & Bose? I've been wating to do this upgrade for a while now - but guess what; PCM - check, Bose - check. Should I be feeling the dread?

The upgraded sound package needs some extra wiring to power the ASK amplifier. It's not insurmountable and there are several people on Planet-9.com that have done this. Actually the instructions I followed were from a guy that did this WITH the sound upgrade. There are 2 different PCM2.1s (amplified or not amplified) so you need to get the right one. I too contemplated that 400 quid one on ebay but that is just the start. For iPod you'd need the Denison gateway or Mobridge adaptor (£300-£500) and a telephone module and a Sat Nav module and ...... this made it highly debatable as an aftermarket mod especially as the Sat Nav is not the best. Hence the decision to go with what I did. All up it cost me less than £600 and it is Garmin SatNav, BlueTooth built in (for music and phone) iPod and also USB stick. If you are going to a 993 these being double din will be too big. This model DNX7240BT is 2009 maps. DNX7260BT is almost identical with 2010 maps. All are European and upgradeable

@ChrisG89 if you're still interested (and if you buy a Kenwood I can offer long distance support and help) search on CDR24 on planet-9 and you should find the guy (S1MMA) who installed a DNX9240BT and had the sound upgrade package and explains which cables you need to patch together.. I am sure he DNX5260BT is similar but has a different look with dials on the side. If you're not after a phone one check out the DNX5200 or DNX7200 models that are NOT Bluetooth by default (yet can be upgraded if needs be).

@Flying Machine For the BOSE I'm afraid you are snookered. The PCM2.1 with BOSE doesn't use copper, but fibre optic and effectively all those components (SAT NAV, BOSE amp, CD Changer, not sure about speakers may still be copper) are on a daisy-chained fibre optic loop (look up MOST bus). I am sure it can be done, but the cost may be prohibitive for the majority.

There is a chap on RennTech who just posted an aftermarket install on a Cayenne, retaining the Bose amp, using a NAV-TV interface for the fibre optic loop.

Thats what is putting me off PCM to be honest Grinnders if I keep my 987. You spend £400 on the unit, then another £600 to get it working and alot of stress along the way.

Thanks for your advise, should know what I'm doing within the next couple of weeks.

That's an excellent job Grinnders and also really does look the part. I did something very similar a couple of years ago with my 987 and was so glad. Decided on a Pioneer hard disk unit that did everything.

Congratulations, I'm sure you're very proud of it.

Not hugely difficult to do, just time consuming. Mine took me a day, and that was without any online info, plus I had a CDR23, so had to cut the aperture to fit the double din
You basically need to bypass the bose amp. There are a few ways to do this, but I just got some pins from Maplin, unlplugged the amp and used that plug to connect the speakers, easily reversible should you need.
The fronts dash and doors are 2 ohms each, so I had to run these in series. The rear sides were 4 ohms, so easier, and the subs were 1 ohm. I removed the shelf, and rerouted them to again run in series. This gave me 2 ohms, which I was able to then get a small amp connected to the sub output.

Just to add some festive editions.

a pair of Boston Acoustics S4S have gone into the the rear deck



and a Kenwood KSC-SW01 sub woofer under the pax seat



sound is now sweeeeet! clap

All I'm saying is if looking, don't rule out an otherwise perfect spec car just because it doesn't have BOSE or Sat Nav
